[Dsg-halla_ecal] New bunker location and rack plan

[Donald Jones]

Hi Marc,
Here is a sketch of the racks. There will be two of them each 0.58m wide and 1.22m tall. Each one will have 8 rows of 3 power supplies. The row to row pitch is 15.3 cm but 3cm is taken up by the aluminum frames so only 12.3 or about 4.8" remains for installation of hardware. I would like to keep the relay box size at 2u or less to allow extra room for air flow if possible. I have also attached a preliminary idea by the designers for placement of the bunker.

Hi Don,

I remember you said you have a document with a drawing of the plan for the radiation bunker and your rack plan. Can you send me those or links.


Regards,
Marc
